Answer

The general guidelines for the construction of a frequency distribution are:
  1. The number of classes should neither be too small nor too large, preferably between 5 to 15.
  2. All class intervals should be of equal size.
  3. Open-end classes should be avoided.
  4. We should preferably classify the data into exclusive series (if it is not specified otherwise).
  5. We should avoid unequal sized class intervals.
